2021-10-19iio: imx8qxp-adc: Add driver support for NXP IMX8QXP ADCCai Huoqing
The NXP i.MX 8QuadXPlus SOC has a new ADC IP, so add driver support for this ADC.

2021-10-19iio: accel: fxls8962af: add wake on eventSean Nyekjaer
This adds ways for the SoC to wake from accelerometer wake events. In the suspend function we skip disabling the sensor if wakeup-source and events are activated. If buffered reads are enabled they will be deactivated before suspend. As the onboard buffer is only holding up to 32 12-bit X/Y/Z data triplets.

2021-10-19iio: adc: aspeed: Get and set trimming data.Billy Tsai
The ADC controller has a trimming register for fine-tune the reference voltage. The trimming value comes from the OTP register which will be written during chip production. This patch will read this OTP value and configure it to the ADC register when the ADC controller probes and using dts property "aspeed,trim-data-valid" to determine whether to execute this flow.

2021-10-19iio: adc: aspeed: Fix the calculate error of clock.Billy Tsai
The ADC clock formula is ast2400/2500: ADC clock period = PCLK * 2 * (ADC0C[31:17] + 1) * (ADC0C[9:0] + 1) ast2600: ADC clock period = PCLK * 2 * (ADC0C[15:0] + 1) They all have one fixed divided 2 and the legacy driver didn't handle it.
